Interleaved step-up converter with a single-capacitor snubber for PV energy conversion applications

, 2013
In this paper, an interleaved step-up converter with a single-capacitor snubber for PV energy conversion applications is proposed. The step-up converter adopts two sets of boost converters with an interleaved fashion and coupled-inductor technology to ...

Active Snubber Circuit for High Power Inverter Leg

, 2009
— High power converters in the conventional 6 pulse configuration with 6 switching elements IGBTs (Insulated Gate Bipolar Transistor) are pushed to the limit of power. Especially the switching loss is high.

Passive circuit configurations for snubber energy recovery in power converters using hard-switched devices

, 1994
The use of snubber circuits on switches in power switching electronic equipment increases circuit efficiency, allowing increased switching frequency and smaller volume due to decreased losses that must be dissipated.

Novel passive lossless soft-clamped snubber for high frequency power converters

, 1993
A novel adaptive soft-clamped snubber is proposed where energy trapped in the snubber is partly transferred to both the load and the DC rail, without any active devices or resistors.

Coupled Inductor-based Soft-switched Boost-Ćuk Converter for Microinverter Applications

In this study, a novel fully soft-switched high step-up dc-dc converter is proposed. The proposed converter comprises the integration of boost and Ćuk converters with the same input inductor and MOSFET, and series-connected output dc-link voltages.

Analysis and comparison of a new passive lossless snubber for high frequency converter application

, 1993
Two variations of a new adaptive turn on/off snubber configuration are developed where energy trapped in the snubber is fully recovered, passively, into the DC rail, in addition to the load, without any active devices or resistors.

Passive lossless turn-on snubbers energy recovery in high frequency power converters

, 1993
This paper describes three passive lossless circuits for recovering turn-on snubber energy, which are applicable to high frequency power converters. The inductive trapped energy, which is load current dependent, is recovered into the DC supply, load or ...
